LIGHTING FIXTURE Application filed October 13, 1930. Serial 1'0; 488,456.

The principal objects of this invention are to effect a uniform diffusion of light and to efiect the distribution of light rays around the fixture in such a manner as to materially 5 reduce the appearance of bulkiness or mass-iveness of the fixture.

The prineip al features of the invention consist in the novel construction and arrangement of light reflecting and light diffusing to surfaces in relation to the light whereby (liffused. light is directed downwardly and reflected light is directed upwardly and outwardly to illuminate and reflect from the major portion of the outer surface of the fix- 15 ture whereby such surfaces are rendered luminous.

In the accompanying drawings, Figure I is a perspective View of my improved pendantfixture. 20" Figure :2 is an enlarged part elevation and part sectional detail of the fixture.

In the construction of fixture herein shown a lamp. holder 1. is suspended by a plurality ofliight' rods 2 from the supporting, flange 3' which is adapted to be secured to or against the: ceiling, x

A light sheet metal shield. 4' somewhat in the form. 04:? the frustrunr of a cone and having a concaved outer surface, is suspended in a suitable manner from the lamp holder 1 by the rods 5. The lower and smaller diameter edge of the shield l is formed with a narrow flange 6 to which are secured a plurality of connecting rods or brackets 7 which are secured to the inner wall of a substantially frustro-conical member 8, the outer surface of which is concaved.

The upper beaded 01' rolled edge 9 of the member 8 is arranged substantially in horizontal alignment with the lower flanged edge 6 of the upper frustro-conical member 4 and a clear space is arranged between the two members. The bottom edge of the frustro-conical member 8 is flanged inwardly and presents a frustro-conical surface 10 sloping upwardly and inwardly.

Mounted upon and rigidly secured to the upper edge of the portion 10 of the member 8 is a reflector member 11 which has a curved reflecting surface arranged in a substantially horizontal position and extending bdween the inner flanged of the member 8 and the im'ier surface of the cen'eaved irustroconieal portion. This reflecting suriacoie are arranged that rays of If ht emanating from the lamp 12 are reflectegfupwardinside of the frustro coni'ea-P shield 4 and 8 o of the same and they are directed upwardly from this refiecti-ng'surfaee tostrike the true tr0conical-' conewved si'rrfaee of the hield 4 which is formed or highly polished metal.

The inward portion 12 of the reflector member 11 is fimged upwardly its a: substantia-lontinuation of the inner frnMWeoRMi! portion re ofthe memberoamt it isprovid'ed with a horizontal flange 13 which supports the rim of a translucent glass ltd-Which is of a she-Flow inverted bow? form. This per mits light rays emanating from the lamp to 7 pass therethrouglr in a diverging ammare direction and the inner rims I0 and 12' are highly polished and reflect thera'ys of light passing downwardly through the peripheral portion: of the glass M.

A plurafit'y' of bracket arm's- H? are sup ported upon the horizentsl flange 1.; and t'end a'bout'the inverted bowl sha'ped glass I4 and carrying at the" ends; portions It? which mounted an open-bottomed semi-bowl shaped v ring; 167 which is coated on the outer side-with a. suitable reflectingmaterfal such as" silver.

The reflecting surface of the inner mirror grass directs rays-of light emanating from the lamp: both downwardly and npward1y,.thoserays .bein directed downwardiy passing through the 14, while these directed upwardly ihtnninate the reflecting surfaee of the ramp Herder 1 and also pass to be redirected downwardly train the ceiiiir It' wilT he" readiiy' understood that light rays" emanating from thela'mp' wit! he spread outwardly, both upwardly and dewn'wanfiy, both from the insideand from the and the outer curved surfaces of the me whieh are of a: reflective ham-ire with be attraetiwly' 1 At fixture such: as described. is very light I in: weight. and. is filmmvery easfly sua- Iii pended, the amount of glass therein being reduced to the minimum.

h at I claim as my invention is 1. A lighting fixture comprising a metallic shield surrounding a lamp and having interior and exterior reflecting surfaces, lightdiifusing means arran'ged below the lamp enclosing the opening in the said shield and a reflector member forming an outward continuation of saidlight diffusing means spaced below said shield and directing rays from the lamp upwardly to either side of said shield.

2. A lighting fixture comprising a pairof spaced substantially frustro-conical shields supported in position in spaced relation to a lamp, one of said shields extending above the other, a translucent glass carried by the lower shield, and means for reflecting rays of light emanating from the lamp upwardly I to the inside and outside of the upper shield.

3. A lighting fixture comprising, a substantially frustro-conical metallic shield having a polished exterior surface, a substantially frustro-conical metallic shield suspended below the aforesaid shield and spaced therefrom, a reflecting surface arranged within the latter shield adapted to direct rays of light upwardly around the exterior ofthe upper shield, a translucent glass extending across the lower shield, and a reflector member arranged between the lamp and the upper shield and having curved reflecting surfaces adapted to direct rays of light both upwardly and downwardly, said reflector member being spaced above said translucent glass to permit the passage of direct light rays to said reflecting surface. 7

4. A light fixture, comprising a metallic shield of substantially frustro-conical form having a concaved outer face, a metallic shield of substantially frustro-conical form suspended from the aforesaid shield and spaced-therefrom, a curved reflecting surface substantially horizontally arranged within ,N the-latter shield and adapted to direct rays of light upwardly-to the inside and the outside of .the upper frustro-conical member, translucent glass diffusing means supported from the lower shield member, areflecting shield spaced above the lower shield and arranged within the upper shield, and a lamp supported within the upper shield. v

."5. A lighting fixture comprising a; lamp holder adapted tobe suspended from the ceiling, a circular metal shield of. substantially frustro-conical form suspended from the lamp holder and spaced therefrom, a substantially frustro-conical metal ring suspended from said shield and spaced from its lower edge, said lower ring having an inwardly and upwardly convergent wall, a reflector member supported in a substantially horizontal position within the'lower suspended member and having an inwardly and upwardly sloping wall and a horizontal flange, an inverted bowl-shaped translucent glass mounted on said flange, a ring-shaped curved reflecting member supported above the flange of the aforesaid reflecting member, and a lamp in the holder arranged centrally above the inverted bowl-shaped member and centrally within said reflecting member and directing rays of light below the encircling reflective member upon the surface of the horizontal refleeting. member to be redirected upwardly between the lower outer metallic member and the frusto-conical shield and to reflect from the outer surface of said upper shield.

6. In a lighting fixture, the combination with a light source, of an upwardly and outwardly flaring shield encircling said lamp, a reflector encircling said light source within said shield and adapted to intercept outwardly directed. rays and direct same upwardly or downwardly, and a reflector spaced below said encircling reflector, said reflector being positioned to receive rays passing laterally below said encircling reflector and direct the same upwardly to either side of said flaring shield.

7. In a lighting fixture, the combination with a light source, of an upwardly and outwardly flaring shield encircling said lamp, a reflector encircling said light source within said shield and adapted to intercept outward rays and direct same upwardly and down- SAMUEL HERBERT MAW.
